GraphQL offers reusable units called fragments, they let you construct a set of fields to include in queries where you need to. Below we have the example 'briefObjectFields, where we return a subset of the possible object fields required for this query.
{
object_193341: object (id:"object-193341"){
...briefObjectFields
},
object_274301: object (id:"object-274301"){
...briefObjectFields
}
}
fragment briefObjectFields on Object{
id
identifier
